The nurse initiates the procedure to remove a client's peripherally inserted central catheter (PICC) when a code blue is called for another client in the unit who collapsed in the hallway while ambulating with the unlicensed assistive personnel (UAP). Which action should the nurse take?

A. You cannot leave a client with an open central venous access. You must secure your current client first. B. Calling for an assistant allows the nurse to ensure the PICC removal is completed safely while also responding to the emergency situation. C. Once a PICC line removal has started, the integrity of the venous system is compromised. Leaving a partially removed catheter or an untended insertion site poses immediate, life-threatening risks to the client, such as air embolism- if the catheter is partially withdrawn and the site is not occluded, atmospheric air can be sucked into the venous circulation during inspiration. If the nurse moves too quickly or awkwardly to leave, there is a risk of the catheter snapping or fraying (catheter embolism). Central venous pressure, though lower than arterial pressure, still requires focused manual pressure and an occlusive dressing immediately upon removal to prevent significant bleeding. While a Code Blue is a maximum priority, the nurse is already engaged in a high-stakes procedure. The UAP who was ambulating the patient is expected to stay with the collapsed client and call for help. Other available staff on the unit will respond to the code. D. Closing the room door is not relevant to managing either situation safely.
